HUB ATTACHMENT Application filed September aiding :11 Keen in the rouutiy of Uhe-hire and tate of New Hampshire. have invented new and useiul improvements in lluh At: t:11l1n1e11i. .ot whirh the following is :1 speciliration.

'lhe il1 ('11liu11 relates to huh attarhing derives and hug for an ohjert to providia tit-rive for retaining :1 huh on the vehicle axle thereof.

The invention enihodies, among othrrl'eatures, a seruring munher for threaded runnertiun with the split end of the axle, harin the usual nut thri-zulodtr mounted thereon and \\"he 1'eh when the meinher is mountedon the axle. the split portions thoreo'i' will h:- extr-uded to look the nut. on the axle. a reinra tilr ring hei 53 emphrvetl to Hul'tmtli) lie. in :1 rmvh's in the axle and extend into :1 gro ve in the said un-n'iher when the Hume-is :1 pplird to the axle to loelil the anemia-r on the axle. thus preventing the a 'ridenial removal ol the nut or hub from the axle.

In the further tliwhmure ol the invention retm-eure to he had to the accompanying drawing; constituting :1 part of this fi' lttfi liti. .ion, in which imilar characters of reference denote eorrespomling parts in all the riews, and in \vhirh:

l ignre l is :1 n-rtieal sertional view of the derive, showing the some applied to. an axle having :1 vehi le huh thereon; Fig; l is an end View: Fig. 2-5 is a pers n-rtire view of the securing nuanher; and Fig.1 is a vertiral Mtllflllitl \ie'n taken i. the line i in Fig. 1.

Referring more partit-ularly to the views, l. diselose a vehiele axle it) on which is :11- rang'ed a \ehiele-huh ll of the usual type the said axle terminating in :1 rednrrd end 'l2 provided with slots 13, extending tough tudinally to form split lt-ortions 14. I

A nut l5 is provided for threaded (onneetion with the split portions 14 of the reduced end 12 of the vehiele axle and the opening formed by the split portions 14- of the said reduced end 12 is preferably of a frusto-conieal shape in order that a frustoconical securing member 16 can be arranged in threaded engagement with the split por- Specitication of Letters Patent.

'5 tiuns 14. it. being readily seen by referring to the views that the split portions are prorillr-d with threads on the inner and outer fares thereof, the threads on the outer faces lot-ingright or left: hand threads and the threat 5 un the inner tau-s heiug OPPOsitP or Opposed thereto, that is to buy, if the threads on the outer faces of the split portions are right hand threads, the threads on the inner faces of the split portions will he lefthand thread or rive versa.

\l'heu the securing member 16 is arranged in threaded engagement with the inner tacos of the pl-it portions 14 it will bereadily seen that the split portions will be extended that the threads on the outer fa es the-reel will hind with the threads on th nut, thusv rigidly lot-king the nut on the rerhu-ed end 1; of the vehicle axle 10 and prtw -nthre" the :u-eidental removal of the huh ll ilwret'roni. The outer end of the securing member 11" preferahiy provided with a diann-trirath' extending groove 1.7, adapted to receive a screw driver or the like therein for the purpose of ar'anging the se "tiring menthol in securing position on the \tillt'lt axle. ing member 16 in position on the axle 10, a eirrular groove LS is formed in the axle a distan -e from the end thereof and a circular 1'. i.\ trn'nnd in the other end of the srruring nzemher l6, :1 contractile springllltt ring 30 heing m-tmnted in the. groove 18 0 that when the securing member 16 is urmanuer mentioned. the ring-2O will snap into the reees t9 and look the seruring ununher l6 rigidly on the reduced portion of the vehicle axle 10. I

llaring thus described my invention, I claim} In combination with a vehicle axle having a redured end slotted to form longitudinally extending- -@plit portions, provided with threads on the outeand inner faces thereof, of a nut having threaded connection with the Raid reduced end and engaging the threads on the outer faces of the split portions. a trusto eonieal securing member for threaded eonnection with the said reduced end, with the threads on the securing mem' ber engaging the threads on the inner faces of the said split portions to expand. the

In order to lock the securranged in position on the axle 10in thesplit portions and bind the same relatively In testimony whereof I affix my signature to the said nut, and a contractile ring 1n presence of two witnesses.

mounted in a groove in the reduced end of 1 r the said vehicle axle and adapted to extend CHARLES gg into a, recess in the said securing member to im lock the said securing member on the said ELMER S. HILDRETH, vehicle axle.
